Application-configurable UVA sensor GUVA-C32SM

Gabi Zech — Wed, 17 Mar 2021 11:00:24 +0000

The UV light sensor GUVA-C32SM includes integrated functions so that it can be easily configured and used for different tasks and applications. The GUVA-C32SM includes a photodiode, amplifier, ADC, digital control logic, and the I2C interface. The GUVA-C32SM sensor is sensitive to UV-A and provides a digital output depending on the intensity. Power consumption can be optimized through the power management feature. Due to its integrated design, the GUVA-C32SM sensor is technically optimal and most cost-effective for mass production. Read more in the detailed datasheet for the GUVA-C32SM sensor…
